I am wondering any of you takes Hawthorn berry extract?

Do you notice any benefits or side effects?

Thanks

I sometimes get chest pain after a bad bout of insomnia. This minimizes the chest pain (Hawthorne is good for the heart).

Hawthorne is good for the heart.

 

Is it really though, or is it snake oil?

 

Have there been any studies or consistent testimony?  How is it thought to work?

Here are a few.

It gave me diarrhea each time I took it. (Multiple sources, tried a few times). Arjuna does not do this but I don't think it's as useful for me as using Citrulline + Glutathione for circulation.
My Calcium score is zero (probably due to Vitamin C plus Concentrated K intake), but I like the benefits for working out. I cycle it or else my BP drops too much, especially if combined with Agmatine.

Abstract
The metabolites of arginine were recently shown to be involved in cardiovascular control. The study addresses the general cardiovascular response of anaesthetized rats to agmatine, a decarboxylated arginine. The relation between two arginine metabolic pathways governed by arginine decarboxylase and nitric oxide synthase was investigated. Intravenous administration of agmatine 30 and 60 microM/0.1 ml saline elicited remarkable hypotension of 42.6+/-4.6 and 70.9+/-6.5 mm Hg, respectively. The hypotension was characterized by long duration with half-time of return 171.6+/-2.9 and 229.2+/-3.8 s, respectively. The time of total blood pressure BP recovery was about 10 min. Dose-dependent relaxation to agmatine was also found in aorta rings in vitro. Both doses of agmatine administered 60-180 min after NO synthase inhibition L-NAME 40 mg/kg i.v. caused greater hypotension 59.0+/-7.6 and 95.8 8.8 mm Hg P<0.01 both compared to animals with intact NO synthase, but this was accompanied by a significant shortening of the half-time of BP return. If agmatine was administered to hypertensive NO-deficient rats treated with 40 mg/kg/day L-NAME for 4 weeks, similar significant enhancement of hypotension was observed at both agmatine doses, again with a significant shortening of half-time of BP return. It can be summarized that the long-lasting hypotension elicited by agmatine was amplified after acute or chronic NO synthase inhibition, indicating a feedback relation between the two metabolic pathways of arginine.

Combined L-citrulline and glutathione supplementation increases the concentration of markers indicative of nitric oxide synthesis
Conclusions

Combining L-citrulline with GSH augments increases in nitrite and NOx levels during in vitro and in vivo conditions.

Hawthorn berries can improve lipid profiles and lead to weight loss. I would expect that to help with heart health metrics. I'd say sometimes the effects feel beneficial, while at other times they feel negative, like you can improve lipid profiles too much and upregulate production.

maybe hawthorn isn't snake oil, more like common oats.  good for you, but not unique or essential
